Barcode halfview

This would be my first time reaching out to ones , who may know right off to issues , I've only began learning basics about my computer a year ago , my screen, coming from a latitude D830 one day just blacks out, no warning shot, eventually mysteriously it comes back , however on the top half of the screen has a normal view and then the middle through the bottom is barcode looking lines running from left and right, with pure luck in guessing , you can click on things down in the abyss , an external monitor does work and can operate it that way, but it's quite a pain, backstory real short , this laptop has been with me , through Iraq 07-09, and afghan 10-11, exposed to sand extreme heat , extreme cold , without even the cooling fan working ( I've never heard it work since owning it.  So I have a bit of an attachment to it and only running windows 7 home on it ( doesn't want to upgrade to windows ten, stubborn s.o.b) , it seems like it could be a quick easy answer , but I'm frazzled for over a year , lack of money consistently prevents normal replace fixes, but it'd be nice to know where to start , anyone please , if ya have a more likely to be cause and solution I'd appreciate it, TY

RE: Barcode halfview

Two possibilities:  bad screen, or bad GPU  (the latter a stronger possibility if nVidia rather than Intel).

Attach an external monitor - if the same fault shows, it's the GPU;  the solution is a replacement system board.  You may have trouble finding one with nVidia again - these had a bad reputation for failing.

If the external monitor is OK on image, chance are the board/GPU is ok -- though it IS possible for nVidia GPUs to fail in such a way that the internal display is faulty while the external is OK.

If you want to keep this model, it may be cheaper to buy a working used system rather than the parts to repair this one.

RE: Barcode halfview

I appreciate the response, the external works fine , back when I first was diagnosing I thought the only option was a new moniter which is pricey for as old as these are, so on another note / question, if you came across another like D830, can you just take a working aspects of that one then , install on my current? Or is that just limited to more non unique parts like monitors and such?

Also one thing I forgot to mention , my iTunes on this computer turns a weird tie dye color to include everything else on the desktop, my newer laptop dies no such thing but is a windows 10 instead of 7 , if this is any kinda clue , or relation to my monitor issue TY

RE: Barcode halfview

Does the system have an nVidia GPU?  If it does, the two symptoms together point to it going bad.
